SmartMedia is just a translation layer. It emulates a block device.
You may use a FAT filesystem on that block device. Most people do. But why
do you expect the driver to have any knowledge of FAT? Does the floppy disk
driver? Does the IDE disk driver?
The FAT (or ext2, or reiserfs, or whatever) file system is an entirely
separate layer from the block device which is provided by the SmartMedia
